Here's my experience with a E-II MPFI Esteem burning IOC Xtrapremium (91 Octane), the engine has to be revved up slightly higher for standard 87 octane petrol:

Economy Driving:

Up shifts:
The idea is to disengage the clutch while taking your foot off the accelerator, smoothly slot up a gear and release the clutch (without accelerating) in such a way that there are no jerks (engine rpm matched with the gearbox rpm) and the engine has enough torque to pull the car in the higher gear (without knocking). Once the car is "rolling" in the higher gear, you can gently accelerate. If you do it right and shift smoothly without forcing the box, your engine rpm will have dropped slightly and it will (almost) match the downshift rpm table (next list).

1st to 2nd: 1500 rpm
2nd to 3rd: 1500 rpm
3rd to 4th: 2000 rpm
4th to 5th: 2250 rpm (half way between the 2000 and 2500 marks)

Down shifts:
The trick is to let the engine coast down in the highest gear possible where a gentle dab on the accelerator would still have enough torque to pull the car in that gear. Once the engine drops below this rpm, shift down.

5th to 4th: 1400 rpm (just below the 1500 rpm mark)
4th to 3rd: 1400 rpm
3rd to 2nd: 1000 rpm
2nd to 1st: 800rpm (the "idle" mark)



I hear ya!

To squeeze the most of your MPFI Esteem, shift when the tach hits 6000 rpm.

I dont know what speeds that transalates to, but I do know that she hits 120Kmph in 2nd ... and you dont need to use the 5th gear... top speed (indicated) is just above 175Kmph in 4th... if you shift up to 5th at 175Kmph, the speed will actually drop gradually to around 165 - 170Kmph.



Watch out: Stomping on the accelerator and redlining an MPFI Esteem in 1st gear can be a real b**ch! With the stock LX (155/80) tyres, this is only good for tyre smoke... even those skinny mopeds will leave you behind on the signal if you try this! (and when and if the tyres finally bite, u end up ramming into 'em from behind!)

With my 185/70 Potenza GIIIs, she still does wheel spins if the surface is anything less than ideal, but now the real problem to watch out for is the torque steer... it could easily send you careening into that skinny moped on the left / right of the car!

Oh... before I forget... dont stomp hard on the gas pedal in 1st on a U turn (unless there's no traffic and you really really want to impress the babe in the red top across the road) ... the car will first shoot out across the road and start a gentle but scary spin... and when you take your foot off the gas in panic, you get a violent "lift off oversteer" spin and end up facing the oncoming traffic... Don't ask how I know this!

Keep redlining the car and the engine will be dead sooner than later.
It is nearly impossible for you to do 120 in second gear unless you have messed with gearbox or engine.
Screeching away the tyres is a good way to increase your budget as the tyres will be bald soon.
btw you sound like a Moped Hunter. Please try and keep more control on the car as it can be dangerous even for you.

Now coming back to Topic.
Change up always at 1000 rpm if you have a car with a nice torque. ofc It takes forever to go fast but you will get good fe.

Why to change down ? Just use brakes to get even better fe.

Not really. I'll just wear out faster, and that's it. Provided you use good oil and know that the engine needs to warm up before you do that.

with MPFI esteem, it is possible, on the speedo at least. [in a stock car]

No matter how much torque your car has, 1000rpm is wrong. You'll damage the engine more than help your FE! also your engine mounts due to the vibrations. That's my take on it.
